Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522976, here are decompositions:
- 103 + 31522873 = 31522976
- 229 + 31522747 = 31522976
- 283 + 31522693 = 31522976
- 307 + 31522669 = 31522976
- 313 + 31522663 = 31522976
- 379 + 31522597 = 31522976
- 613 + 31522363 = 31522976
- 619 + 31522357 = 31522976
Showing the first eight; more decompositions exist.
